IPhone 7 update firmware

For iPhone 7 firmware, there are the following ways: via Wi-Fi, via iTunes or Finder (automatically or manually at choice), Recovery mode and DFU mode. We will now consider each of these methods in more detail.

Firmware via WIFI

The easiest way to reflash the iPhone 7 is automatic firmware over the air, ie over Wi-Fi. To do this, go to the settings - general - software updates. In this menu, you will see the available software for your device. It only remains to confirm the installation. After a successful software download, the iPhone will prompt you to enter the password of your device and will reboot. After a while, the iPhone will automatically update to the latest firmware.

Automatic firmware via iTunes or Finder

If for some reason it is not possible to update via Wi-Fi, it is possible to use this method. To get started, install iTunes on Windows. Connect the iPhone to the PC and in the device management section there, select the firmware method: update or restore the device. With a simple update after confirmation, the next steps are identical to updating via WIFI. If the update fails, you need to use device recovery. When restoring the device, iPhone will restore the factory settings and all device data will be deleted, but before these actions, iTunes will offer to create an archive of your data that can be restored later.

Through the Finder the steps are similar.

Manual firmware via iTunes or Finder

If you can't update automatically, you can follow these steps.

First we need to download the appropriate firmware manually. Connect the device to the computer, go to the device management section. Hold down the Shift key on Windows or Option on MacOS and select the update method. After clicking, a Explorer window will pop up in which you need to select the appropriate firmware file. It remains only to wait.

Recovery mode

If the device does not work properly and you want to clean the device as much as possible, you need to use this method. You must first turn off the device. Then, by pressing the volume down key, we connect the device to the computer. Keep this until the computer icon appears on the iPhone. After that, a window will appear on the PC that there is a problem with the iPhone, which will offer such solutions as recovery or upgrade. The following steps are similar to those described above in the iTunes or Finder firmware method.

DFU (Device Firmware Update) mode

When through Recovery is not updated to restore the device you need to enter it in DFU mode. To do this, turn off the device and connect it to the computer.

Press the power button for 3 seconds. Press the volume down button for 10 seconds in parallel with the power. After that, holding the volume down button, release the power button and hold for 5 seconds. A window will pop up on your computer notifying you of an iPhone connection. Next, choose the recovery methods described above. If an apple or computer is displayed on the smartphone during these manipulations as in Recovery mode, then you need to go through all the stages again until they correspond to the above.
